I have experimented a issue in Http HDS live streaming.I know that when you broadcast a live streaming, is normal to generate cache file at address /streams/_definst_/ in “livestream” folders. I configured the event.xml file like this:











In normal, this cache “livestream” folder for simple http streaming in first two days was with only 450 Mbps and showing after one hour are replacing and remaining during all day in 450 mbs of usage. After one week in one example account running without none interruption in all that days and today I checked that this same folder is with 15 Gbs.


The same test I done in Adaptative Streaming in other account with three bitrate taxes (150, 350, 720 kbps) that will generate in this case three folders of cache. In first two days, all that three folders used only 1.2 Gbs of disk. After one week broadcasting direct without interruption, the three folders are with 150 Gbs used. In last time after two weeks was with so so 450 Gbs used.


I checked the Adobe instructions to configure the Apache cache at address and Well. After done it the cache root after three days was enorm wi so so 150 Gbs of usage.


I was checking in livestream folder, and there are generating many files by day. Fragment cache files from today, yesterday, the day before yesterday.... Group files for each day. Then cause this is using many disk space in server.


Anyone can help me to solve this issue, becouse it is using many disk in our server.


I hope for any help

    are you sending the right string trhough the RTMP  URI?





    if you are using the default "adbe-live-event=liveevent" then this is the source of that issue.  Especially if there is no Event.xml containing <EventID>liveevent</EventID>
